INTRODUCTION
1.1 Background
High voltage testing is a test that consists of the application of a voltage higher than the rated voltage for a specified time for the purpose of determining the adequacy
against breakdown of insulating materials and spacing under normal condition. Test is done for proofing test of a new apparatus, maintenance of older equipment and as
evaluating method to develop insulation systems. Stresses of the insulation will withstand under a various operating conditions should be determined and the response of insulation
should also be determined in order to design and testing a high voltage insulations.
Basically, impulse test is just about: i.
Impulse test is used to evaluate any device insulation against lightning impulse. ii.
Impulse test can be implemented by using a special procedure such as a routine test.
iii. Impulse test consists of impulse voltage and impulse current test.
iv. Impulse test are usually done on a high voltage device such as a transformer,
cable, surge arrester, insulator and many more. v.
Impulse voltage can be represented by a unidirectional waveform that rise rapidly to its peak value and slowly fall back to zero voltage.
vi. Impulse voltage test are consists of an Impulse Voltage Generator, voltage
divider, shunts, control system and a measuring instrument with a calibration equipments
1.2 Problem Statement
To know the effect of high voltage impulse voltage when it is applied to the high voltage insulation glove on a various conditions
1.3 Objectives
The objectives of this project are:
i. To perform a high voltage impulse voltage test on the high voltage
insulation gloves. ii.
To familiarize with high voltage lab testing and procedures. iii.
To know high voltage lab equipment.
1.4 Scope of the research.
This project has been confined to four relatively simple aspects which they are:
i. Learning and exploring in a way to produce the impulse voltage and to run
an impulse voltage testing on the insulation glove with the four different condition which are normal condition, oily condition, wet condition and
dirty condition. ii.
Perform an impulse voltage valued less than 100kV.
